SIX-WHEEL TRUCK.

Application filed January 8, 1918, Serial No. 210.907.

. invention, such as will enable others skilled in the art to which it appertains to make and use the same.

.My' invention relates to trucks for railway cars, with particitlar reference to six-wheel trucks adapted to carry very heavy loads,

awhile at'the sam e time constructed in as simple and direct a manner as possible and of the fewest parts.

One of the objects of my invention isto provide a truck of the character described without equalizing bars or movable levers to l transmit the load from the car body to the.

wheels, and also to provide a structure which is stiff, strong and so proportioned that it is unnecessary to arrange the transoms or equivalent portions at different. distances from the pairs of end wheels as compared with their distances from the center wheels in the attempt to equalize the loading on the various wheels.

I also provide side frames so constructed and braced that the load from the car body is distributed on the six wheels so that each of the wheels has to carry substantially the same load and its due proportion of the total. In order to facilitate this, I. provide springs of ample capacity but of sufficient yielding movement, preferably over each of the journal boxes, so that if, on account of the irregularities in the track, one or a pair of the wheels is disposed to assume more than its due share of the load. the springs above it will yield, thus allowing the other wheels to take their shares of the load and thereby equalize the load pressure on each of the wheels. Another object of my invention is to provide inner arch bars or arc-hes of simple but strong construction, adapted to transmit the load from the bolster to the side frames through the transoms in the simplest way.

Another object of my invention is to so arrange the truck framing that the central pair of wheels and their axle, as well as the Specification of Letters Patent.

other wheels and axles, moved from the truck bling the truck frame.

My invention also comprises other objects as will hereinafter more fully appear.

Having thus given a general description of my invention, make the matteranore clear, refer to ihe annexed two sheets of drawings, which form part of this specification, and in which like characters refer to like parts.

Figure l is aplan view of my truck as a whole; Fig. 2 is a side elevation thereof; Fig. 3 is a longitudinal sectional elevation on the line III-III of Fig. 1; Fig. 4 is a central transverse sectional elevation on the line IVIV of Fig. 2; Fig. 5 is a transverse sectional elevation on the line VV of Fig. a transverse sectional elevation through the wheel piece, showing a slightly modified form of brace plate connecting the transom to the wheel piece and also showing a modified form of brake hanger support; Fig. 7 is a plan view of the portions corresponding to those shown in' Fig. 6; Fig. 8 is a transverse -sectional elevation through the wheel piece showing another slightly modified form of combined brace may be easily rewithout disassemplate and brake hanger support; and Fig.

9 is a Fig. 8.

Referring now to the characters of referplan view of the portions shown in v "106 on the drawings :1 is the wheel-piece,

which is of inverted trough section pro vided with upper flange 2, web portions 3 and slightly projecting lower lateral flanges 4; 5 are the truck transoms, each composed of'a deep trough section provided with alower flange 6, side web portions 7 and upper laterally projecting side flanges 8, these transoms being provided with top cover plates 9 riveted thereto as shown. These truck transoms are secured to the underside of the wheel pieces 1 by means of the channel shaped hangers 10, the flanges-1'1 of which are riveted to the webs of each of the, transomsas shown, while the channel web's 12 are riveted to the webs 3 of the wheel pieces; 13 are the inside arch bars or arches,

I will now in order to strong, being the deepest where the'hending stresses are greatest andreducing in depth toward the ends where the-bending stresses are the least. The ends of these arches 13 of the bolster.

rest upon and are secured to the transoms 5 r as illustrated. These inside arch bars, or archesare also adapted to receive side bearings on the outer portions of their upperfaces, smooth portions being provided in this location as shown for this purpose.

Any form of side hearing maybe mounted on these arch bars and I havetherefore not llustrated this detail.

The central transverse bolster is formed of, a pairof trough sections 19, each provided with a lower flange 20, side webs 21,

'upper laterally projecting flanges 22 and with a cover plate 24 riveted to the lateral flanges as shown. The-trough sections of the bolster are connected to the inside arch bars or arches by the channel or trough shape hangers 23, the webs of which are riveted to the webs 15,0f the arches and the flanges of which are riveted to the webs 21 On the upper central portion of this bolster, I mount a center plate 25, provided with extending portions 26, which are riveted to the outer lateral flanges of the bolster, as indicated.- It should be noted that I use two trough shaped members for the central bolster, one arranged on each side of the center axle of the car and no portion of this bolster or other part of the truck frame passes below the axles, thus allowing the center pair of wheels and their axle to be removed from the truck in a similar manner to that of removing the end axles,

- and this is a feature of my invention, as it .well adapted to its purpose, the flange porconduces to ease and economy of maintenance and repairs. I

The end axles are 27, the .wheels are 28, and the central axle is 29. The side framesare each composed of a wheel piece 1 of inverted trough shape, as heretofore described,

with the transoms hung securely to and below the same, and in. addition to these portions, I also provide diagonal brace or tension members 30,. the upper portions of which are of trough section, with their flanges 31' riveted to the webs 3 of the wheel piece 1, this trough portion gradually merging into a flat'portion 32, which is arranged to contact .with the lower flange 6 of the transoms and may be riveted thereto, as shown, or may merely contact with the lowerportion of the transoms if desired. The construction of this'tension member 30 is such that it is very.

' tions 31 being adapted to contact directly with the webs of the wheel piece, while the lower flat portion is adapted to contact directly with the lower flange of the transom shaped portion merges gradually into the flat portion, as illustrated. This makes a very stiff and strong structure, one of good appearance which is also adaptedfor use in fourwheel trucks. The web portion of the upper ends of the tension member is indicated as 33. Immediately adjacent the upper ends of the tension members '30 I provide trough shaped guide bars-3a, each-having a web portion 35 and flanges 36, which latter. are adapted to be riveted to the webs 3 of the .wheel piece 1. These flanges 36 are preferably secured by means of countersunk 'rivets, so as to provide flush surfaces on their interior,'and these, together with the surfaces of the webs of the wheel pieces, pro- 1,138,632,.dated May 18, 1915. The springs inthese pockets are of such design as to have ample movement in use, while at the same time they are of strength sufficient to carry the loads imposed upon them, and as the truck passes over the track, each of the springs yields to a greater or less extent, de-

pending upon the .amount of irregularity nvheels, and this is possible by'reason of the vi'de spring pockets 37, one over each ournal 'which it meets; so that the loads-are virtu- I ally equalized on each of the journals and strength and stifl'ness of the side frame, due

-to the wheel piece 1, the brace and tensionniembers 30 and; their attachments. By

mounting-the springs in these pockets, they are also protected from 'theweather, accu-- mulations of water, snow, ice, dustor other materials and, are consequently in good condition for'performing their functions at all times.

For. the sake of clearness of illustration l have only shown one set-ofsprings, but wish it understood that similar frictioir springs are provided in each of the pockets 37.

Another feature of my invention is that my truck is adapted to utilize standard journal boxes 39, the upper sides of .which are provided with projecting lugs 40, the edges of which are adjacent'to 'and hold in relativewposition bythe guide bars 34:. For the purpose of retaining the journal boxes in the truck, thelower ends of the flanges of the guide bars 34 are provided with holes and the bolts 41 arei-nserted therethrough and held in position by means of the split keys 42. By-reason of this construction the entire truck frame with its wheels and axles can be lifted and moved'as a .whole when desired, and when it is necessary to remove a pair of wheels and their axle and journal boxes, the bolts 41 are, withdrawn and the truck can bdtheii lifted froin "any pair of wheels and x e -Q s3" is a bracket-' extension, preferably ormedof pressed"steel,.lprovided with a 1' yrivets, "shown, the outer end of the ketbeingoffse't, 'as illustrated, and pro portion 53 of which is trope- I one riveted to the top of the Q "transcends illustrated, the flange portion 542 beingriveteddirectiy to the web 3 of the wheelyp-iece', esillnstrated. This therefore foririswi erystiff and eliicient brace or set plate connection between the transom no "end the wheel piece, which serves to square the tincl; and .ltee in she 5e imtwithstend- "top flfapnge i irwehs and 46, thewehshe' f 111;" secured to thewebs'of the wheel P1828:
